Developmental changes induced by glucocorticoids treatment in breeder quail (Coturnix coturnix japonica)

The effects produced in offspring by corticosterone treatment to breeder quail were investigated. The breeders received corticosterone orally every day during 7 days. The total dose administered was 3.15 mg/quail/7 days. The quail from treated breeders have a decreased rate of body growth during the experimental period. The studied metabolic and nutritives parameters were smaller than the control group, however, the relative indices were similar. The breeders treated with corticosterone produce quail smaller than controls, but the pattern during the growth period is similar, there it can be observed by the same relative indices.
